Abstract

See full text

A multiple-pane insulating glazing unit may include multiple panes of transparent material and a layer of electrically controllable optically active material that provides controllable privacy for the glazing unit. Despite efforts to fully black out the multiple-pane insulating glazing unit by switching the optically active material from a transmissive state to a privacy state, the glazing unit may exhibit some residual direct visible transmission. In some examples, the multiple-pane insulating glazing unit may include a light emitting element positioned to direct light at the layer of optically active material to address this issue. Light emitted by the light emitting element may reflect and mask residual visibility through the electrically controllable optically active material.
